D.C. Mun. Regs. tit. 5, r. 5-E2311
The results of tests administered by the D.C. Public Schools or under the auspices of the Board of Education shall not be considered determinative of the innate ability of individual students.
Tests results may be used as a factor in the ongoing process of determining the best placement of students in the educational program and assessing students' individual instructional needs, based upon current competencies and skills. Test results may also be used as a factor in the evaluation of student and program performance.
The provisions of this section shall not preclude the use of diagnostic tests or other tests connected with the assessment and evaluation of learning problems or learning deficiencies, or the evaluation and placement of students in programs for the handicapped.
